摘要
大岗山水电站工程规模巨大,高拱坝、高边坡、高地震烈度的工程特性决定了工程建设难度大、工程技术复杂。在工程建设过程中,针对高烈度地震区拱坝抗震安全、峡谷坝肩高边坡开挖、右岸边坡卸荷稳定、大坝基础处理、混凝土温控等重大技术难题,积极落实解决方案,为确保工程建设安全有序推进提供了强有力的技术支持。经过9年多的建设,在参建各方的共同努力下,工程所面临的重大技术问题已基本解决。详细论述了相关重大技术难题的解决方案,可供同类工程参考。
Dagangshan Hydropower Station is characterized as large scale,high arch dam,high bank slope and high earthquake intensity,making it encounter with significant construction difficulties and challenges. Aiming at some key technical issues such as high dam anti-seismic safety,dam abutment excavation in valley,unloading stability of right bank slope,dam foundation treatment,concrete temperature control,effective measures were studied to provide technical support for the smooth construction of the project. Through 9 years,effort,the mentioned problems have been solved basically. The adopted measures and solutions are presented in detail.
